ANTISKIDDING DEVICE.

Specification of Letters latent.

Patented Jan. '7, 1913.

Application filed January 24, 1912. Serial No. 673,071.

To all whom t may concern Be it known that I, WILLIAM H. SNYDER, a citizen of the United States, residing at Ashbourne, county of Montgomery, State of Pennsylvania, have invented a new and useful Antiskidding Device, of which the following is a specification.

My invention consistsof an improved device for preventing skidding of the wheels of powerdriven vehicles, which may be -readily attached and detached to and from the wheel. r

It further consists of improved means for tightening such device upon the rim and tire of a wheel. j

It further consists of improved means for retaining the clip vin position.

It further consists of other novel features of constructiomjall as will be hereinafter fully set forth. j l The annexed drawings and the following description set forth in det-ail one mechanical form embodying the invention, such detail construction being but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings- Figure 1 represent-s a side elevation of parts of the rim, tire and spokes of a wheel, showing my 'device in posit-ion. Fig. 2 represents a transverse section of said parts. Fig. 3 represents a side elevation of parts of the rim, tire and spokes and a section of the defice taken on the line in Fig. 2. Fig. 4 represents a section onthe line g/-y in Fig. 2.` F ig. 5 represents a detail view of Ythe inner end of one limb of the clip and Fig. 6 represents a 'detail view of clamping means for securingthe device in a wheel having flat spokes.

Similar numerals of reference indicate corresponding part-s in the figures.

Referring to the drawings :-1 designates the rim of a vehicle wheel having the tire 2 and spokes 3, all of which parts may be of anydesired or suitable construction. The anti-skdding device is preferably formed of the plate or ban'd 4 or any suitable or de sired construction, and preferably provided with ears or projections 5 which serve to bite or engage with the roadway in order to prevent skidding or slipping of t-he wheels. Suitable means are provided for attaching and firmly holding the band in pobers 7 adjacent the upper side edges there-`v of and each of which members is provided.

with the inclined shoulders or cam faces S. 9 designates an inner frame adapted to interfit with the outerframe 6, and which is provided with the members l() on the sides thereof adjacent the lower portion, `and each of which members is provided with the inclined shoulders or cam face 11, facing the cam faces 8.

12 designates a laterally movable separat-or which is provided on opposite sides thereof with the oppositely inclined shoulders or double' .cam members 13 for1n, ing a wedge member, the inclined shoul` ders or cam faces of which vare adapted to contact with or rideiupon, as will hereinafter be explained, the. cam faces 8 and 11v of the side members 7 and 10.

14 designates a bolt or -pin which passes through a suitable opening in the outer frame 6, and is movablein the slot 15 in the end of the inner frame 9, said pin or bolt 14 being in suitable connection with the separator 12 in order that by the actuation of the pin 14, the separator 12 may be moved to cause the two rframes to hare relative sliding movement with respect to each other.' In the present instance, this connection is accomplished by means of a nut 16 on t-he threaded end of the bolt which is seated between the ears 17, carried by the separator 12. A spring 18 bearing upon said nut and a suitable portion ofthe separato-F12 serves as a resilient bearing be,- tween the parts.

'As will be seen more particularly from Fig. 2, the pin or bolt 14 passes through a snitableopening in the band 4 and serves to hold the same in position. A second screw or bolt 19 also passes through the band 4 and is held in place by a nut 20 in order to prevent lateral or swinging movement of thel band 4 with respect to the frame 6 and the tire 2 land-so that it will be held firmly in radial position when the parts are locked. The opposite end of the band is held in place by the bolt 21 passing through the outer frame 6 and seated in the slot 22 in the inner frame, in order thatJ the latter may freely move with respect tothe outer frame. The band 4 is also provided with the pins 23 I the pin 145,' the separator or expander 12 will be actuated in order to cause the cam members 13 thereof to' be moved in a proper dircction, as seen in Fig. 2, to the yright in orderv to cause thecam face thereofto ride upon the cam faces of the members 7 and 10. This will cause 'relative movement between the frames and will force the' relative cam faces, carried thereby, apart moving the innenframe toward the rim 1 and so against the same, and forcing thefouter frame 6 away from the rim, and as-the' band is connected with the outer frame, it will readily be seen that the movement will cause the said band 4to firmly grip the tire 2, and the said band and parts will be firmly and `securely held in position.

I may desire to provide a device for assist'ing in holding the parts in position, and in Fig. 2 I haveshown a bolt or screw 25 in engagement with a cross bar 2,6, carried by the outer frame 6, and which bolt or screw is adapted to rest in a boss or other suitable means 27, on the inner frame, said screw or bolt ,25 being common to said frames and independent of said expander and serving to hold the parts in their adjusted` position and assist in carrying the strain.

It will `be seen that the device'is simple in construction, positive in action, and-can easily be placed in'position or removed from the wheel. Any 'number of these devices may be used around a Wheel that may be necessary toprevent skidding or slipping thereof.

I have shownin Figs. 1 and 3 the side Walls of the outer frame 6 as inclined to conform to the inclination of the spokes 3, but this may'not be necessary'in all nstances, andany suitable form of outer frame may be employed which will accomplish the desired results. As shown, the outer frame as it is moved away from the rim l will have a Wedging action with the spokes 3, but will assist in holding the same in posit-ion.

In some instances I may provide a construction shown in Fig. 6, where the spoke 28 is of a flat type as seen,'and to this end I'provide vears orlugs 29 on the outer frame 6, in which ears I mount the-levers 30, each of which is provided with a slot 31 through which passes a screw 32 which is carried by the outer frame 6 and a set screw 33 `carried by the lever ,at the opposite end thereof and bearing, as will be apparent,-

upon the frame 6. One end of each lever 30 is placed in engagement with a spoke 28, and by proper manipulation of the screws the said levers will rmly grip the spoke,

which latter will be firmly held between thesaid levers and the frame 6, as is evident.

Having th ,A described my invention, what' I claim as n yw and desire to secure by Let-.

ters Patent, is:-

1. In a vehicle wheel, a rim, a tire,l a band adapted to seat on the tire, a frame to which the band is connected, a second frame adapted to engage the lsaid rim, a wedge member engaging 'both frames, and means for actuating said wedge member laterally for separating said frames.

v2. In a vehicle wheel, a-rim, a tire, a band adapted to engagelthe tire, a frame to which the band is connected and having inclined shoulders thereon, a second frame movable with respect to said first frame `and having inclined shoulders, an expander intermediate said frames and having inclined shoulders thereon adapted to engage the inclined shoulders of both frames', and means for laterally moving said expander forradially separating said frames. t

i 3. In a vehicle wheel, a rim, a tire, a band adapted to engage the tire, a frame to which the band is connected and having cam faces thereon, a second frame movable with respect to the first frame and having cam faces thereon, an expander having cam faces thereonadapted to engage the cam faces of the two frames, means for actuating the expander, and a resilient. connec-l tion between the expander and the aetuating means.
